HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 828, 703, 20 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 828, 703, 20 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 498, 828, 703, 20 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 498, 828, 703, 20 is 1.
HCF(498, 828, 703, 20) = 1
HCF of 498, 828, 703, 20 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 828, 703, 20 is 1.
Highest Common Factor of 498,828,703,20 is 1
Step 1: Since 828 > 498, we apply the division lemma to 828 and 498, to get
828 = 498 x 1 + 330
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 330 and 498, to get
498 = 330 x 1 + 168
Step 3: We consider the new divisor 330 and the new remainder 168, and apply the division lemma to get
330 = 168 x 1 + 162
We consider the new divisor 168 and the new remainder 162,and apply the division lemma to get
168 = 162 x 1 + 6
We consider the new divisor 162 and the new remainder 6,and apply the division lemma to get
162 = 6 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 498 and 828 is 6
Notice that 6 = HCF(162,6) = HCF(168,162) = HCF(330,168) = HCF(498,330) = HCF(828,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 703 > 6, we apply the division lemma to 703 and 6, to get
703 = 6 x 117 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 703 is 1
Notice that 1 = HCF(6,1) = HCF(703,6) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 1, we apply the division lemma to 20 and 1, to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 20 is 1
Notice that 1 = HCF(20,1) .
